Nostalrius Begins - Quality wow vanilla realm (1.12)

I understand this may not be the correct forum to place this under but I could really use a GM's services to dismount me off this Hippogryph so I can begin healing the instance I was headed to while being summoned. The summon bugged the flying mount and now I cannot dismount, enter the instance or land at the Flight Master I have tried these scenarios already.

Character Name - Byble - Alliance

Thank you.

GM Fixed issue very timely, Thank you.
